Teoría de Legibilidad como parte de la comprensión del espacio urbano

The present annex summarises the premises used in the estimation of market shares the explanation and justification of which are included in the analysis.

1. Available information

ICP-ANACOM had access to the following relevant information for the purposes of estimating market share:

- Information on ADSL broadband accesses, with the following level of disaggregation:

o Quarterly wholesale, disaggregated by operator, by MDF and by class of

service (with respect to the “Rede ADSL PT” wholesale offer);

o Quarterly wholesale, disaggregated by operator and by MDF (with respect to the ORALL);

o Six months retail, disaggregated by operator, by class of speed and by NUTS II;

o Quarterly retail on the number of IP TV customers of PTC (presentation of results).

- Information on cable modem broadband accesses (retail) disaggregated by operator. 2. Need for compatibility with respect to the various available data

The detail of the analysis in geographic terms requires that determined presumptions are made for the purposes of estimating market share, particularly in order to ensure compatibility between the various available data.

Therefore, and taking into account that it was decided to define the MDF/AP as the relevant geographic unit, in the estimation of market share the options and premises detailed below were used.

3. Assumed options and premises

In the estimation of market shares, in the context of both the wholesale and retail markets: - The wholesale data was used with reference to ADSL accesses, with the distribution

of broadband accesses with respect to the MEO service of PTC181 by MDF, it is amused that these accesses, in 2007, were associated with only one exchange with co- installed operators (principal MDFs with ADSL2+ technology) and taking into account the proportion of broadband accesses in these MDFs;

- The data referring to broadband access supported through cable modem is distributed in the first place, by municipality, depending on the number of customers of the cable television service (supported over cable distribution networks) of each operator, and secondly, according to the MDFs existing in the municipality depending on the number of FTS accesses of each MDF182.

It is assumed that the coverage area of the attendance points and the area covered by municipality exactly coincide.

Retail information

Besides the base scenario referred to in the previous sector, valid in a scenario where wholesale regulation is maintained, assessment is made of the retail market shares taking into account the absence of regulation, assuming that:

- Scenario 1: The accesses supported through the “Rede ADSL PT” and OLL wholesale offers are counted as broadband accesses of Grupo PT;

- Scenario 2: The accesses supported through the “Rede ADSL PT” and OLL wholesale offers will be attributed to Grupo PT, in the first place, depending on the number of customers who only have FTS183, while the remaining accesses184 are distributed among Grupo PT and the cable distribution network operators depending on the weight of the “own” accesses of each operator.

181 _{It is noted that these broadband accesses are not included in the information with respect to the wholesale offers.}

182 _{To this purpose it is noted that in cabled municipalities, the percentage of cabled households is around 90%, in other} words, the cabled area is not concentrated in a reduced area, whereby it is reasonable to choose to distribute the broadband accesses supported through cable modem over all the MDFs included in the municipality. Another option would be distribute these accesses over only the principal MDF(s) of the municipality, which would result in an additional premise that is complicated to quantify.

183 _{That is to say, it assumed that the customers who do not have cable television and have contracted the FTS will support} broadband services over the local loops of copper pairs.

Wholesale information

Market for the wholesale supply of broadband access

In estimating the market shares in the market for the wholesale supply of broadband access and taking into account the base data referred to in section 3.1, the concept of internal supply was used, whereby it was considered that:

- The “Rede ADSL PT” and MEO accesses contracted by the companies of PTC are

counted as wholesale accesses of Grupo PT;

- The broadband accesses supported over the networks of each cable distribution

network operator are counted as wholesale accesses of these operators;

- The “Rede ADSL PT” accesses provided by PTC to third parties are counted as

wholesale accesses of Grupo PT;

- The OLL accesses provided by PTC to third parties are counted as wholesale accesses of each one of these (third) operators.

Market for the wholesale (physical) network infrastructure access at a fixed location In estimating the market shares in the market for the market for the wholesale (physical) network infrastructure access at a fixed location, use was also made of the concept of internal supply, with consideration given, for the purposes of estimating market share, to all active accesses at a fixed location, irrespective of the support infrastructure, allowing the use of broadband accesses. Accordingly account was taken of the following:

- All active accesses of the cable distribution networks, irrespective of the type of service contracted185, are counted as wholesale accesses belonging to each one of the cable distribution network operators186;

- All accesses in use with reference to the PTC network are counted as the wholesale accesses of Grupo PT (including accesses unbundled to third parties)187;

- Any other active accesses, supported over other infrastructure, such as for example, FWA, are counted as wholesale accesses of the operators possessing such accesses. Each basic or primary ISDN access was counted as a single access.

185 _{Except for DTH accesses which do not support broadband access services.} 186 _{Quarterly information, disaggregated by operator and municipality.} 187 _{Quarterly information, disaggregated by MDF.}
